For a Colour (Japanese) Tamagotchi
1. I want the screen not to turn off after 1 minute, the screen can go less bright, but still be on ( Number 2 explains how the batteries would last)
2. Rechargable, you are supposed to leave your tamagotchi charging while it's sleeping, it will get nightmares and call for attention if its not charging (forcing you to charge it so it doesn't run out of battery)
3. It would have a led light on a corner that turns on when the Tamagotchi calls for attention
4. Headphones slot, I would want to hear the beeps of my Tamagotchi without having to bother other people in the bus
5. Bluetooth, Old Mobiles have bluetooth, New Mobiles have bluetooth, Laptops have bluetooth, Tablets have Bluetooth. Why would you use NFC when Bluetooth is a lot more common and easier to set up?
6. Trees, I love having trees on my TMGC+C. is one of my favourite features, it shouldn't have been removed
7. More Variety of downloadable games, most of them are recolors from other ones
8. Downloadable Characters AND Growth Paths comming from previous versions (you could get your tamagotchi to evolve in the same way as the Entama/Uratama or as in the P1, for example)
9. Downloadable Icon Backgrounds (The ones in the 4U are all so ugly...)
10. Custom house, not just the living room
11. A lot of items to collect with cute animations
12. Conncet with Tama-Go Land (And also raise it's characters)
13. Pause feature please
14. Can store food on the friedge instead of having to go to restaurants like it used to be
15. Door icon takes you to a map so you can walk to the destinations you want to go yourself
That would make a perfect tamagotchi lol
For a Black/White (English) Tamagotchi
1. BACKLIGHT, PLEASE, BACKLIGHT
2. Tamagotchi Related items to collect
3. More resistant screen
4. Non Recycled games (Maybe Recycled Games as an extra, but please, new games)
5. Variety of Characters, Maybe chosen by a poll. (And Tama-Go Land Characters Please)
6. Family (Like in the Tama-Go)
7. Background shop (Like in the Tama-Go too)
8. Oldies as bad care transformations (You can keep your character for as long as you want if you take good care of it)
9. Variety of shells AND faceplates
10. Cute Sprites (Seriously, some characters get ruined because of the ugly sprites, even when they are cute characters)
